runtests -g explained

  automatically detect if that is the case, and it will use the ../memanalyze

  script to analyze the memory debugging output.

Debug:

  If a test case fails, you can conveniently get the script to invoke the

  debugger (gdb) for you with the server running and the exact same command

  line parameters that failed. Just invoke 'runtests.pl <test number> -g' and

  then just type 'run' in the debugger to perform the command through the

  debugger.

Logs:

  All logs are generated in the logs/ subdirctory (it is emtpied first

  in the runtests.sh script)
